The other codes are for bearing ID, build date and assembly plant. Information on these items are more difficult to find. With enough research you can get this info if it's important to you.

Thanks for all the great info. I am still wondering what the 386D at the end of the second line means.

That's either the assembly plant code or the date it was built. What year is the truck?
